H-beam is flat, I-beam is slanted. Of course, the difference between the two is not just the difference in the inner side of the flange (also called "leg"). H-beam can be divided into piles, columns and beams according to the width ratio of the flange to the web, while I-beam is basically used as a beam. H-beam has the widest application range in steel structure buildings.

Galvanized steel pipes are welded steel pipes with hot-dip or electro-galvanized layers on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life. 

Prestressed concrete is to make the steel bar configured in the tension zone of the component bear a tensile force in advance and generate pretensile stress.

What is the difference between Q195, Q215, Q235, Q255 and Q275 in terms of material?

Carbon structural steel is the most used steel, the largest number of often rolled into steel, profiles and profiles, generally do not need to be heat-treated direct use, mainly for general structure and engineering.

I-beams, also known as steel beams, are long strips of steel with an I-shaped cross-section. I-beams are divided into ordinary I-beams and light I-beams. It is a section steel with an I-shaped cross-section.

 Rebar, also known as reinforcing bar or rebar, is a crucial component in construction and infrastructure projects. It plays a vital role in providing strength and stability to concrete structures, making it an essential material in the construction industry. In this guide, we will explore everything you need to know about steel rebar, from its properties and types to its applications and benefits.

Square tubes, a versatile and indispensable material, are playing a pivotal role in global construction and modernization efforts. With their wide range of applications and adaptability, square tubes are categorized into four main types based on their cross-sectional shapes: profiles, plates, pipes, and metal goods. This classification simplifies their production, ordering, delivery, and management, making them a cornerstone of industrial and infrastructural development.

 In recent years, galvanized color coated sheets, also known as color coated steel or pre-painted galvanized iron (PPGI), have emerged as a game-changer in the global building materials and furniture markets. Their unique combination of durability, aesthetic appeal, cost-effectiveness, and sustainability has made them a preferred choice for architects, builders, and designers worldwide.

Steel structure is a structure composed of steel materials and is one of the main types of building structures. 

Section steel is a kind of bar steel with a certain cross-sectional shape and size, and is one of the four major varieties of steel (plate, tube, profile, wire).
